Brian Duperreault, Chairman and Chief Executive Officer of ACE Limited, commented: "If I had to single out a defining characteristic of the second quarter, I would point to the significant increase in our capital strength. Everything that happened this quarter contributed to our capital resources. We posted record income, generated positive gains in both our fixed income and equity portfolios, completed the conversion of $311 million of mezzanine securities to common equity and completed the issue of $575 million of perpetual preferred shares. The result was a 22% increase in shareholders' equity for the quarter from $6.7 billion to

$8.2 billion."

(1) Income (loss) excluding net realized gains (losses) on investments and the tax effect of net realized gains (losses) on investments is a common performance measurement. We believe this

presentation enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business. We exclude net realized gains (losses) on investments because the amount of these gains (losses) is heavily influenced by, and fluctuates in part according to, the availability of market opportunities. This measure should not be viewed as a substitute for net income determined in accordance with generally accepted accounting

principles (GAAP).

(2) Diluted book value per Ordinary Share is Ordinary shareholders' equity and net proceeds from assumed conversions of outstanding in-the-money options divided by the sum of shares

outstanding and the number of options assumed issued.

(3) Debt prepayment expense in 2002 of $11 million ($7 million, net of income tax) has been reclassified to other income (expense) to conform to the current year presentation.
